Pre-1.5: "nTube, the privacy friendly media center."
1.5.0: "nTube, the [insert marketing term here]."
1.5.1: 'nTube, "because why not make fun of developers?"'
1.5.2: "nTube, because EVERYTHING is content."
1.5.3: "nTube, take a hint."
1.5.4: "nTube, NUMBER #1 CONSUMER PRODUCT CHOICE"
1.5.5: "nTube, the proud owner of 14 tons of fireworks."
1.5.6: "nTube, 5 year anniversary edition."
1.5.7: "nTube, please pay up."
1.5.8: "nTube, somehow it still works."

These will be removed in 1.5.9, since there is no point in continuing considering nTube's release cycle. (shame)
